<p><P>PROBLEM TO BE SOLVED: To provide a bearing plate capable of increasing the strength of a wooden building and reducing damage by aftershocks. <P>SOLUTION: This bearing plate 11 comprises an outside plate 12 for completely closing a lateral surface of a rectangular frame body 31 composed of horizontal members 32 and 33 and columns 34 and 35, and an inside plate 13 which is integrated with the outside plate 12 and fitted into a hollow portion 36 in the frame body 31. The bearing plate 11 is attached to the frame body 31 by means of a fixing nail 21 so that the frame body 31 can be displaced into a parallelogram shape by a horizontal load, the outside plate 12 faces the frame body 31. In this case, the outside plate 12 resists that displacement; an end surface of the inside plate 13 is brought into contact with the columns 34 and 35, so as to suppress the deformation of the frame body 1. When the deformation of the frame body 31 becomes too great, the upside horizontal member 32 is placed on the top surface of the inside plate 13, and can bear even an excessive vertical load. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
